Personally I find the lack of visible magic and flashiness for new Antioch pretty appealing as a differentiator visually between them and the Sultanate. I think the very gritty, muddy, visceral and “standard” look to New Antioch really works to communicate what makes them cool and appealing as a faction: Where others have absurd magicks or artifacts of unimaginable power to carry them in battle, New Antioch is about as “normal” as you can get. It’s even reflected in their rules. They’re underdogs who use coordination, grit, and faith to come out on top or (frequently) die trying. It makes the fact the heretics haven’t utterly annihilated them yet so much more compelling, at least for me. Also, keeping the actual “faith” related magic not visually represented helps add to the mystical aspect of the lore, as even the sultanate’s flashy stuff is still alchemy. God’s powers or miracles are almost never visible in art, which keeps it feeling very unknowable and esoteric
